(cept 1 which was just clogged/broken fan). Problem with dead cards, it's usually an electrical/chip failure, so fixing it becomes a bit complicated.
The reason people don't bench at the res you want, is because the cards you're looking at are so damn powerful, it'd be an instant 60+fps on every game out on the market. Also, cards give different performances at low res and high res, a card could outperform all others at 1920x1200 but be dead last of it's tier at the res you want, needless to say it'll still be damn powerful, just not an accurate comparison. Plus, these cards were meant for high resolution gaming, so anything of this generation would max out every game for you.
Add: Anyways I was looking at the specs for your rig, assuming they're up to date, you seem to be rather CPU bottlenecked, why spend the money for a GTX260 when you could upgrade the CPU+mobo and get a Geforce 9 Series card for a nice boost in performance overall.
